MidNite Solar DIY Series

GaRayGaRay Registered Users Posts: 1
Anyone used one of the new "all in one" devices where the charge controller, inverter and 120 volt DC charger is one unit? MidNite Solar now makes several of these devices, available at NAWS, as do several other unknown companies. Remember when we purchased separate components for HiFi stereo reproduction then manufactures combined the components... 8 track, cassette and turntable all in one! The quality suffered, IMO.  Is that the case with the new solar "all in one"?


Thanks for your comments!

    Does anyone know if the MN3024DIY (and similar) are transformer based?  TIA

    The entire DIY line of inverters,   appear to be High Frequency designs.   Vic

    Thanks.  I could not find a weight for the items.

    Hi Mike,

    If the weight still matters to you:

    DIY 3024 weighs 17 Lbs
    DIY 3548 weighs 24 Lbs

    You are correct that the power out vs weight is a very good indicator Low vs High Frequency conversion design.

    Surprisingly inexpensive for Midnite products.

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric, 540 ah @24 volt AGM battery bank. Plenty of Baja Sea of Cortez sunshine.

    Yes price seems good. But these units have a scarey resemblance to the Renogy and Powmr which are unreliable chinese brands. I hope its not not the same unit with the midnite name slapped on.

    Yeah, over on another forum, there's been some pretty certain ident that these are rebranded Chinese items. Kinda sad, but maybe it's OK if Midnite backs them up.

    Yes, MidNite offers support for these Chinese inverters and controllers.  They are not Renogy or Powmr.

    China is getting too good at this stuff and with support, it can help a lot of DIY'ers to get into renewables.

    The next group of these will be ETL listed.


  • mahendramahendra Solar Expert Posts: 161 ✭✭
    Well that's a bit comforting to know

  • boBboB Solar Expert Posts: 995 ✭✭✭✭
    Even a Sol-Ark is a Chinese inverter with their name on it   :)  (Deye)

    Yes .Another post indicated the same Deye.has good reviews in austrialia

    One of the statements Midnight makes about the unit is that it has "excellent surge capacity".  I've gone through the whole manual and find no reference to what that capacity is?  Is it 200% for 5 seconds, or 200% for 16 milli-seconds?  I'm more inclined to believe it's 16 ms?
    They do mention that the unit can start a "2hp loaded motor", but they in no way indicate what that starting surge is?
    I'm guessing that this unit would be a good choice for powering a garage or other secondary structure, but not where you'd be expecting to run motor-driven power tools, compressors, ect.  That would need a stout low-frequency inverter like a Radian or Conext/XW.  Will be OK powering a cabin where you just need cold beer to watch TV.

    I haven't seen this.   Do you remember where you saw/heard this ?

    I do know that the new MidNite inverters are surging like crazy in house  though !

    It's in the brochure.  If you click on the link above, two sub links down the page are the product brochure, and the product manual.

    Tried to do a cut and snip, but it didn't show up in the response.

    Well I have been pretty skeptical of Midnite's DIY stuff and a matter of fact all of the new Chinese inverter ,but I must say that there are several brands such a growwatt,phocos, deye etc that are high frequency but matches the surge performance of low frequency inverters. 
    It's just technology improvements real
  • boBboB Solar Expert Posts: 995 ✭✭✭✭
    Yes, China is getting WAY too good at this stuff !   They still miss the boat on some aspects though and the US, Germany, etc will still have their place.  At least I hope so !

    Will Midnite Solar have a prewired e-panel available for the DIY line?

    I think much of it is integrated into the Unit, As it contains charge controller, transfer switch, you might be better off wiring a small box for a big inverter breaker and a PV input breaker.

    AC output and generator bypass would be nice also. That could also be done externally. Sure would keep the footprint small with an e-panel.

    Formxwhat Midnite is saying on their forum ,they will .

    mahendra could you provide a link? I could not find any talk of an e-panel getting developed for the DIY series.

    The DIY series inverters do not have a high enough absorb voltage setting to accommodate all battery chemistries such as NIFE. I would think adding a few more volts in the software wouldn't be all that hard?

    My XW inverter does not have high enough voltage, but with NiFe, I don't have to fully charge them, my PV controllers can get them all the way full when the sun eventually returns

    It requires better internal equipment too handle larger voltage ranges. I suspect making it inexpensively requires/necessitates the minimal range. I understand Most inverters can't handle the wide range due too the inefficient charging nature of NiFe batteries. At around 65%  efficiency, I always recommend people avoid them for solar electric systems. I think only Magnum and some Schneider inverters have the range for NiFe.

    My old Trace PS series will do up to 33 volts input which should safely get me 32.4 v on the charge controller, at least I hope it will, should know shortly.
